AstraZeneca discontinues 2 Phase III evidence trials for Lokelma
The decision to discontinue the trials is not due to safety concerns and the positive benefit-risk of Lokelma does not change in the approved indication.
AstraZeneca has decided to discontinue the STABILIZE-CKD and DIALIZE-Outcomes Phase III evidence trials for Lokelma (sodium zirconium cyclosilicate). The decision was made due to substantially increased enrolment timelines and low event rates, respectively, which made it prohibitive to deliver study results within a timeframe to meaningfully advance clinical practice.
STABILIZE-CKD and DIALIZE-Outcomes trials are part of the CRYSTALIZE evidence programme, which includes clinical and real-world evidence studies researching the potential benefit of Lokelma in the management of hyperkalaemia (HK) across the cardiorenal spectrum.
Sharon Barr, Executive Vice President, BioPharmaceuticals R&D said, “Our ambitious CRYSTALIZE programme continues to generate evidence to improve the current management of hyperkalaemia, which we believe leads to better outcomes for cardiorenal patients when a potassium binder is included in their treatment regimen. Lokelma is the leading branded potassium binder globally and continues to benefit a broad hyperkalaemia patient population to achieve rapid, sustained potassium control and is well tolerated.”
The Company will work with investigators to ensure the necessary follow-up with patients.
Lokelma is approved for the treatment of a broad HK patient population in 56 countries worldwide. The decision to discontinue the trials is not due to safety concerns and the positive benefit-risk of Lokelma does not change in the approved indication.
Hyperkalemia (HK) can be a chronic condition characterised by high levels of potassium in the blood, generally defined as greater than 5 mmol/L. Patients with high potassium levels are at significant risk of cardiac arrhythmias, which can lead to cardiac arrest. Worldwide there are about 840 million and 64 million people living with CKD and HF respectively, who are at an estimated two to three times higher risk of hyperkalemia. RAASi therapy is guideline-recommended to slow down CKD progression and reduce CV events, but the dose is often lowered or therapy is discontinued when HK is diagnosed. This has been shown to negatively impact patient outcomes, with mortality rates doubled for patients with CKD and HF whose RAASi had been down-titrated or discontinued compared to patients on maximum RAASi dose.
